act 11:1PETER VINDICATES HIMSELF BEFORE THE CHURCH IN JERUSALEM FOR HIS PROCEDURE TOWARDS THE GENTILES. (Acts 11:1-18)
the apostles and brethren . . . in Judea--rather, "throughout Judea."
act 11:2they . . . of the circumcision--not the Jewish Christians generally, for here there were no other, but such as, from their jealousy for "the middle wall of partition" which circumcision raised between Jew and Gentile, were afterwards known as "they of the circumcision." They doubtless embraced apostles as well as others.
act 11:3Thou wentest in . . . But Peter rehearsed the matter, &c.--These objectors scruple not to demand from Peter, though the first among the apostles, an explanation of his conduct; nor is there any insinuation on Peter's part of disrespect towards his authority in that demand--a manifest proof that such authority was unknown both to the complainers and to himself.
act 11:12we entered the man's house--No mention of Cornelius' name, much less of his high position, as if that affected the question. To the charge, "Thou wentest in to men uncircumcised," he simply speaks of the uncircumcised "man" to whom he had been divinely sent.
act 11:13seen an angel--literally, "the angel," for the rumor took that definite shape.
act 11:14Who shall tell thee words whereby thou and all thy house shall be saved--The historian makes the angel express this much more generally (Act 10:6). So also the subsequent report of it by the deputies and by Cornelius himself to Peter (Act 10:22, Act 10:32). But as Peter tarried with Cornelius certain days, and they doubtless talked over the wonderful scene together, perhaps this fuller and richer form of what the angel said was given to Peter; or the apostle himself may have expressed what the angel certainly designed by directing them to send for him. Observe, "salvation" is here made to hang upon "words," that is, the Gospel message concerning Christ. But on the "salvation" of Cornelius, see on Act 10:34-35. On that of his "house," see on Luk 19:10.
act 11:16Then remembered I the word . . . John . . . baptized with water; but ye shall be baptized with the Holy Ghost. Forasmuch then, &c.--that is, "Since God Himself has put them on a level with ourselves, by bestowing on them what the Lord Jesus pronounced the higher baptism of the Holy Ghost, would it not have been to withstand God if I had withheld from them the lower baptism of water, and kept aloof from them as still 'unclean?'"
act 11:18held their peace and glorified God--Well had it been if, when Paul afterwards adduced equally resistless evidence in justification of the same line of procedure, this Jewish party had shown the same reverential and glad submission!
Then hath God also granted to the Gentiles, &c.--rather, "granted to the Gentiles also." (See a similar misplacement of "also" in Heb 12:1). To "grant repentance unto life"--that is, "such as issues in life" (compare Co2 7:10, "repentance unto salvation")--is more than to be willing to pardon upon repentance [GROTIUS]. The case of Cornelius is so manifestly one of grace reigning in every stage of his religious history, that we can hardly doubt that this was just the feature of it which they meant here to express. And this is the grace that reigns in every conversion.
act 11:19THE GOSPEL BEING PREACHED TO GENTILES AT ANTIOCH ALSO BARNABAS IS SENT THITHER FROM JERUSALEM, WHO HAILS THEIR ACCESSION AND LABORS AMONG THEM. (Act 11:19-24)
they which were scattered abroad upon the persecution that arose about Stephen--and who "went everywhere preaching the word" (Act 8:4).
travelled as far as Phenice--that part of the Mediterranean coast which, commencing a little north of CÃ&brvbr;sarea, stretches northwards for upwards of one hundred miles, halfway to Antioch.
and Cyprus--(See on Act 4:36). An active commercial intercourse subsisted between Phenice and Cyprus.
and Antioch--near the head of the northeast coast of the Mediterranean, on the river Orontes, and containing a large colony of Jews, to whose religion there were there numerous proselytes. "It was almost an Oriental Rome, in which all the forms of the civilized life of the empire found some representative; and through the two first centuries of the Christian era it was what Constantinople became afterwards, 'the Gate of the East'" [HOWSON].
act 11:20some of them were men of Cyprus and Cyrene--(see on Luk 23:26); as Lucius, mentioned in Act 13:1.
spake unto the Grecians--rather, "the Greeks," that is, uncircumcised Gentiles (as the true reading beyond doubt is). The Gospel had, from the first, been preached to "the Grecians" or Greek-speaking Jews, and these "men of Cyprus and Cyrene" were themselves "Grecians." How, then, can we suppose that the historian would note, as something new and singular (Act 11:22), that some of the dispersed Christians preached to them?
act 11:21a great number believed--Thus the accession of Cornelius and his party was not the first admission of uncircumcised Gentiles into the Church. (See on Act 10:1.) Nay, we read of no influence which the accession of Cornelius and his house had on the further progress of the Gospel among the Gentiles; whereas there here open upon us operations upon the Gentiles from quite a different quarter, and attended with ever growing success. The only great object served by the case of Cornelius was the formal recognition of the principles which that case afterwards secured. (See on Act 15:19-29.)
act 11:22sent . . . Barnabas . . . as far as Antioch--implying that even on the way to Antioch he found churches to visit [OLSHAUSEN]. It was in the first instance, no doubt, a mission of inquiry; and no one could be more suitable to inquire into the proceedings of those Cyprians and Cyrenians than one who was himself a "Grecian" of Cyprus (Act 4:36), and "a son of consolation."
act 11:23when he . . . had seen the grace of God--in the new converts.
was glad--owned and rejoiced in it at once as divine, though they were uncircumcised.
exhorted them all that with purpose of heart--as opposed to a hasty and fickle discipleship.
they would cleave unto the Lord--the Lord Jesus.
act 11:24For he was a good man--The sense of "good" here is plainly "large-hearted," "liberal-minded," rising above narrow Jewish sectarianism, and that because, as the historian adds, he was "full of the Holy Ghost and of faith."
and much people were added unto the Lord--This proceeding of Barnabas, so full of wisdom, love, and zeal, was blessed to the great increase of the Christian community in that important city.
act 11:25BARNABAS, FINDING THE WORK IN ANTIOCH TOO MUCH FOR HIM, GOES TO TARSUS FOR SAUL--THEY LABOR THERE TOGETHER FOR A WHOLE YEAR WITH MUCH SUCCESS, AND ANTIOCH BECOMES THE HONORED BIRTHPLACE OF THE TERM CHRISTIAN. (Act 11:25-26)
Then departed Barnabas to Tarsus for to seek Saul--Of course, this was after the hasty despatch of Saul to Tarsus, no doubt by Barnabas himself among others, to escape the fury of the Jews at Jerusalem. And as Barnabas was the first to take the converted persecutor by the hand and procure his recognition as a disciple by the brethren at Jerusalem (Act 9:27), so he alone seems at that early period to have discerned in him those peculiar endowments by virtue of which he was afterwards to eclipse all others. Accordingly, instead of returning to Jerusalem, to which, no doubt, he sent accounts of his proceedings from time to time, finding that the mine in Antioch was rich in promise and required an additional and powerful hand to work, he leaves it for a time, takes a journey to Tarsus, "finds Saul" (seemingly implying--not that he lay hid [BENGEL], but that he was engaged at the time in some preaching circuit--see on Act 15:23), and returns with him to Antioch. Nor were his hopes disappointed. As co-pastors, for the time being, of the Church there, they so labored that the Gospel, even in that great and many-sided community, achieved for itself a name which will live and be gloried in as long as this world lasts, as the symbol of all that is most precious to the fallen family of man:--"The disciples were called CHRISTIANS first in Antioch." This name originated not within, but without, the Church; not with their Jewish enemies, by whom they were styled "Nazarenes" (Act 24:5), but with the heathen in Antioch, and (as the form of the word shows) with the Romans, not the Greeks there [OLSHAUSEN]. It was not at first used in a good sense (as Act 26:28; Pe1 4:16 show), though hardly framed out of contempt (as DE WETTE, BAUMGARTEN, &c.); but as it was a noble testimony to the light in which the Church regarded Christ--honoring Him as their only Lord and Saviour, dwelling continually on His name, and glorying in it--so it was felt to be too apposite and beautiful to be allowed to die.
act 11:27BY OCCASION OF A FAMINE BARNABAS AND SAUL RETURN TO JERUSALEM WITH A CONTRIBUTION FOR THE RELIEF OF THEIR SUFFERING BRETHREN. (Act 11:27-30)
came prophets from Jerusalem--inspired teachers, a class we shall afterwards frequently meet with, who sometimes, but not necessarily, foretold future events. They are classed next to apostles (Co1 12:28-29; Eph 4:11).
act 11:28that there should be great dearth throughout all the world--the whole Roman empire.
which came to pass in the days of Claudius CÃ&brvbr;sar--Four famines occurred during his reign. This one in Judea and the adjacent countries took place, A.D. 41 [JOSEPHUS, Antiquities, 20.2,5]. An important date for tracing out the chronology of the Acts. (But this subject is too difficult and extensive to admit of being handled here).
act 11:29Then the disciples, every man according to his ability, determined to send relief, &c.--This was the pure prompting of Christian love, which shone so bright in those earliest days of the Gospel.
act 11:30sent it to the elders--an office well known to be borrowed from the synagogue; after the model of which, and not at all of the temple, the Christian Churches were constituted by the apostles.
by the hands of Barnabas and Saul--This was Saul's SECOND VISIT TO JERUSALEM after his conversion.
